STACK-ROOF.

Specification of Letters Patent.

Patented Sept. 10, 1918.

Application filed. November 14, 1916. Serial No. 131,299.

To all whom it may concern:

Be it known that I, WJLLIAM R. narrow, a citizen of the United States, resldmg at Geneva, in the county of Fillmore and State of Nebraska, have invented new and useful Improvements in Stack-Roofs, of which the i} grain stacks, feed racks and the like.

The primary object of the invention is to produce a device of this character wherein the boards or plates may be easily, quickly and securely connected without the employment of nails or analogous securing elements, and wherein the edges of the boards or plates will lap to provide a perfect shed for water, etc., and whereby to provide a covering that will effectively prevent the contents thereof from the elements.

In carrying out my invention it is my purpose to produce stringer members of flexible material, such as strips of wire, to bend the ends of the same upon themselves whereby the first board or plate of the cover may be thus secured to the stringers, and to provide hooks of a novel construction which may be easily and quickly arranged upon the stringers to support the remaining boards or plates of the cover.

It is a further object of the invention to produce anadjustable stack roofing chain whereby boards or plates of varying widths may be easily, quickly and securely attached and wherein all of the boards or plates will have their edges lapping.

It is a still further object of the invention to produce a stack roofing chain which may be arranged either upon the interior or upon the exterior of the roof and which will effectively support the boards. or plates of the roof when the chain is in either of such positions.

An additional object is the provision of astackroof of this character which may be partially or even entirely assembled while lying flat upon the ground and which may subsequently be grasped at its ends by two operators and positioned over a stack to be roofed without thenecessity of either operator climbing upon the stack itself.

With the above and other objects in view the improvement resides in the construction, combination and arrangement of parts set forth in the following specification and falling within the scope of the appended claims.

In the drawing:

Figure 1 is a perspective view of a stack roofing constructed in accordance, with the present invention,

Fig. 2 is a sectional view through the same taken in a line with one of the chains,

Fig. 3 is a transverse sectional view upon an enlarged scale approximately on the line 33 of Fig. 2,

Fig. 4 is a perspective view of one of the stringer members of the chain, and

Fig. 5 is a similar view of one of the hook members for the chain.

While my improvement may be employed in the construction of buildings, such as sheds or the like, and which structure may be either of a temporary or permanent nature, the improvement is primarily designed, as illustrated in the drawing, to facilitate in the erection of roofing or covering members for grain or hay stacks, the device being particularly useful in this direction inasmuch as the covering can be easily and quickly applied to effectively protect the stack againstthe elements and as easily and quickly removed from the stack, when occasion requires. Furthermore, the construction is such that the boards or plates forming the covering may be piled one upon the other, when the device is not in use, to occup'y only a comparatively small space for transportation or storage, and wherein the chain construction may be likewise folded and arranged in the same package with the boards or plates.

In carrying out my invention I employ any desired number of stringer members 11. Each of the members 1 is preferably constructed from a single strand of suitable wire and has its opposite ends bent upon itself and continued in a line with the main strands, as indicated by the numerals 2, whereby to receive the end boards or plates 3, or whereby the hooks provided by the bent portions 2 may be associated so that the stringers may be of any desired length. The flexible stringers are, of course, adapted to be arranged around the stack 4 which is to be protected by the covering, and in order to insure the stability of the device flexible elements, such as auxiliary wires, may

be passed through the stack at the bottomthereof and have their ends secured to the bent ends or hooks 2 of the stringers .1. i.

After the end or face boards 8 arealranged upon the stringers, as described,"I insert upon each of the stringers a hook 5 that is adapted to overlie the upper edges of the boards 3. 7 All of the hooks .employed in my improvement are of a similar con struction, but, of course, the same may vary p in proportion in accordance with the boards orplates with which they are adapted to" engage.

Each of the hooks 5 is preferably constructed from a single strand ofwire and includes a looped portion 6 that is adapted "to engage with the stringer'l. The arms of the loop 6 are bent angularly thereof, as indicated by the numeral'7, the said bent portions 7 being in parallelism and the ends of the said portions 7 are bent outwardly, as at 8, in a line'parallel to thearms' of the loop and are from thence continued upwardly to provide the outer spring members 9. It will thus be not-ed that the body of each of the hook members is substantially U-shaped in side elevation, each of said sides being similar, but, of course, spaced away from each other, and this construction is particularly desirable as the spaced members of each of the hooks provide for the "ready insertion of said hooks over the [will overlap thus effectively shedding rain or moisture therefrom and consequently protecting the stack from the elements.

An important feature of this'devlce is that a partlal or even the entlre assembling "of the parts may be accomplished While the Copies of this patent may be obtained for stringers andboards are lying flat upon the groundand that the entirely or partially assembledroof may be grasped at the ends by two operators and bowed upwardly for 'dispo'sition over a stack without the necessity of either operator climbing upon the stack itself. Furthermore, it will be noted that the. device when disassembled may be very 'easily and conveniently stored away and Will occupy but slight space.

It is, of course, to be understood and as clearly lllustrated in; the drawings, the hooks 5 upon the opposite sides of thestack are reversely positioned and while two of such reversely positionedhooks might be employed for securing the edges of the central or top board or plate, and while such an arrangement might be particularly desirable especially whenthe top of the roof is in the nature of a bendable member, such as athin metal plate, I have found it de- I sirable to centrally secure to the stringers 1 a tie wire 11 and to bring the said wire around the plate or board next to the top plates or boards and to twist the ends of said wire 11 over the said top boards or plates, as clearly. illustrated by the drawings, and by this means it will be noted that the top boards or plates have their edges overlapping the boards or plates adjacent thereto.

Having thus described the invention, what I claim is:

1., A stack roof comprising a plurality of boards disposed in arcuate form and arranged with the lowermost edge of each" board in overlapping relation toth'e uppermost edge of the next adjacent board, a

horizontally disposed top board having its side edges disposed in overlappingrelationf to the upper edges of the adjacent boards at both sides thereof, a plurality of flexible stringers disposed upon; the -undersides of said boards and; having their lower endsbent outwardly' and upwardly in encircling i relation to the'lowermost boards, the, extremity of each stringer being colled upon itself above the top edge of the lowermost board, and a plurality of hooked members straddlingly and slidably engaged upon said I/ I stringers, and engaged beneath the lower edges of said boards. I 1 V 2. A stack roof comprising a plurality of. flexible stringers, spaced boards associated with the ends of the stringers, the end of each stringer being bent upon itself into en circling relation to the associated board and having its extremity coiled upon itself and a plurality of other boards detachably connected with said stringers and arranged in overlapping relation to said 'first named boards and to each other. V

3. A stack roof comprising a plurality of flexible stringers each bent upon itself at its end to provide a loop and having its extremity coiled upon-itself, boards disposed within said loops, and a plurality of other boards detachably connected with said stringers and disposed in overlapping relation to said first named boards and to one another.

In testimony whereof I aflix my signature. 7 WILLIAM R. ARNOLD. WVitnesses:
